Fig. 1 is a vertical, sectional view of a portion of an absorber equipped with a spraying apparatus exemplifymg the invention; and Fig. 2 is a sectional view on an enlarged scale on line 2-2 of Fig. 1.

Referring to the drawings, and` to the em` .bodiment of the invention which is selected for exemplification, there is shown in Fig. 1 a vertical shell or casing 3, into the bottom vof which the natural gas may be admitted, a gas outlet pi e 4 being provided for the escape of the gas a ter being subjected to the action of the oil sprays. The casing is provided with a cover-plate 5, to which is attachedan oil inlet conduit 6, having a portion 7 which depends within the chamber presented by the casing. The conduit presentsone or. more` herein a plurality of spray orifices 8, arranged in vertical series, and herein ro es- ,sively decreasing in diameter toward t e ottom. In practice, the combined capacity of the outlet orifices corresponds in a general i Way to the capacity of the principal portion of the conduit.

The characteristicsl of each of the individual s raying devices will now be de-- scribed, re erence being had to Fig. 2. Each spraying device presents a central passage 9, with which the outlet orifice 8 communicates by way of a chamber 10 about a central passage. This lateral chamber is conveniently formed 'Within a lateral projecting, depending flange, or skirt, 11, conveniently cumstances of the particular installation.

formed integrally with an internally threaded stem 12 and an externall threaded stem 13, as by a laterally extending web 14 connecting the latterstem with the skirt, and presenting a plurality of passages 15. In the present example, the internally threaded stem is larger in diameter than the externally threaded stem, thereby to facilitate carrying out the idea of connecting together a series of spraying devices proa0 -gres'sively decreasing, in size lengthwise of the series, as by the use of a series ofl intervening spacers or connecting devices 16, each internally threaded to receive the externally threaded stern on .one spraying device, and ex- '65 ternally threaded at its other end to enter .the internally. threaded stem on the next adjacent Vspraying device. The `len h of these spacers may be such as to suit t e cir- In the present example, the outlet orifice of each spraying device -is adjustable in width,"thereby to vary its capacity, and in the present example, this is conveniently accompli'shed by the provision of an axially adjust- 75 able collar or sleeve 17, presenting a laterally projecting flange 18, which is arranged for cooperation with the flange 11. Adjustment of this sleeve is conveniently accomplished by threading the 'same onto theV externally so threaded stem 13, on which the' sleeve can be rotated in the properdirection to produce the desired adjustment.- When this adjustment has been obtained, it may be preserved -by utilizin the spacer 16 as a lock-nut e5 screwed `en wise against the sleeve. In the case of the lowermost sleeve of the series, there is provided an internally threaded cap 19, whlch closes that end of the conduit and is threaded ontothe externally .threaded stem 13, the cap inA this case serving as a lock-nut for the vadjustable sleeve of the adjacent spraying device. v

In o eration, when the spraying ap aratus is use in connection with an absor er for natural gas, oil is supplied under pressure to the inlet of the conduit 6, and issues from the several orifices in the form o'f conical sprays in the directions indicated bythe arrows in Fig. 1.v The gas in passing in an upward di- A rection through the several sprays is freed of gasoline and oil vapors, which are then precigitated to the bottom of the apparatus, w

ere suitable disposition is made of them, as b the use of a tra not shown herein, which disc arges the liquid contents, without permitting the esca e of gas.

Having thus escribed one .embodiment of the invention, but without limiting myself thereto, what I claim and desire by Letters Patent to secure is:

1. In a spraying apparatus, a conduit having a central passage, a laterally disposed annu a r fiange forming with sa1d conduit an annular chamber, and another laterally disposed annular flange spaced from the firstmentioned flange closing said chamber and forming an orifice affording an outlet from a said passage by way of said annular chamber, the last-mentioned flan e being carried by a sleeve having screw-treaded engagement with said conduit for movement lengthwise thereof, said conduit including two parts having screw-threaded engagement with each ot er, and one of such sleeve endwise.

2. In a spraying apparatus, a conduit having a central passage, a laterally disposed flange forming with said conduit one or more lateral passages leading therefrom, and an outer sleeve formin with said flange an annu# lar outlet orifice ag said sleeve being movable lengthwise of said conduit to varIy the width of said outlet, another outer 4s eeve engaging the first-mentioned sleeve endwise, and an inner art having'screw-threaded engagement wit both of said sleeves.

In testimony whereof, I have signed my name to this s ecification.
